Users of Windows who have set the Automatic Updates option to "Download updates for me, but let me choose when to install them" were surprised to find that the latest WMF patch had overridden these settings and not only installed the patch, but rebooted the machines as well.

I was wondering why my machine had rebooted for no apparent reason last week after getting out of bed, I couldn't find ANY explanation. It seemed to have rebooted at ~11pm and I noticed it at 7am the next day, scanned the event viewer logs and found nothing, now it's obvious what did this.

So my machine was running for 8h without doing anything because the software it had been running before the reboot of course wasn't running anymore. I saw something about an update but didn't make anything out of it since I believed I knew it wouldn't install anything without my permission.
